Question

What is the solution to the equation x + 2.15 = –3.2?

Answer 1

First of all subtract 2.15 from both sides.
x+2.15−2.15=−3.2−2.15
x=−5.35

Answer 2

Subtract 2.15 from both sides. When you substract a negative number with a positive you are essentially "adding" both numbers together.
So -3.2 - 2.15 = -5.35
This would be the solution as now x = -5.35

When plugging in -5.35 for x you get: -5.35 + 2.15 = -3.2

Answer 3

thanks
